516989 divided by 81 
Our goal is to divide 516989 by 81.

Let's proceed to step 1:
If we divide 5 by 81, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 81

Going ahead to step 2:
The number 81 fits into 51 0 times, leaving a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 51, we get 51.
Fetch the next digit (6) from the dividend, attach it to 51 and continue: 516 / 81

On to step 3:
If we divide 516 by 81, we get 6 and a remainder of 30.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtracting 486 from 516 leaves us with 30.
Take the next digit (9) from the dividend and append it to 30, then repeat: 309 / 81

Going ahead to step 4:
81 goes into 309 3 times with a remainder of 66.
Put 3 as the next digit of the answer. 
Result so far: 63.0
If we subtract 243 from 309, we get 66.
Grab the next digit (8) from the dividend, add it to 66, then carry on: 668 / 81

Let's proceed to step 5:
If we divide 668 by 81, we get 8 and a remainder of 20.
Use 8 as the next digit of our solution. 
Result so far: 638.0
Subtract 648 from 668 to get 20.
Append the next digit (9) from the dividend to 20 and continue with: 209 / 81

On to step 6:
If we divide 209 by 81, we get 2 and a remainder of 47.
The number 2 becomes the next digit in our result. 
Result so far: 6382.0
Subtract 162 from 209 to get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

On to step 7:
81 can be fit into 470 5 times, resulting in a remainder of 65.
Write down 5 as next digit of the result. 
Result so far: 6382.5
Deduct 405 from 470 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Advancing to step 8:
When dividing 650 by 81, we get 8 with a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 6382.58
If we subtract 648 from 650, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 9:
If we divide 20 by 81, we get 0 and a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 6382.58
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 10:
81 can be fit into 200 2 times, resulting in a remainder of 38.
Use 2 as the next digit of our solution. 
Result so far: 6382.5802
The remainder is 38 after subtracting 162 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 11:
When dividing 380 by 81, we get 4 with a remainder of 56.
Use 4 as the next digit of our solution. 
Result so far: 6382.58024
Subtract 324 from 380 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 12:
81 can be fit into 560 6 times, resulting in a remainder of 74.
The number 6 becomes the next digit in our result. 
Result so far: 6382.580246
The remainder is 74 after subtracting 486 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Let's proceed to step 13:
81 goes into 740 9 times with a remainder of 11.
The next digit of our result is 9. 
Result so far: 6382.5802469
The remainder is 11 after subtracting 729 from 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 14:
If we divide 110 by 81, we get 1 and a remainder of 29.
Write down 1 as next digit of the result. 
Result so far: 6382.58024691
The remainder is 29 after subtracting 81 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

The final result is 6382.58024691 with a remainder of 2.9e-08.
